Comparative study of the fingerprint between two mammalian species and the human

Nora A. Aljalaud*, Haifa M. AL khaldi

This study aimed to examine the morphological and electronic description of the ventral surface of the finger’s skin or what is known by fingerprint using fingerprint ink, fingerprint scanner and scanning electron microscopy in humans (Homo sapines), baboon (Papio hamadryas) and squirrels (Tamias striatus). The fingerprint is considered as the most common biometric feature. Fingerprints are based on the formation of papillary projections deployed on the surface of the skin take different forms and seem separated by grooves called groove lines.

The present results showed that fingerprints of the five fingers of the human are differentiated from each to another; and this is what has been observed when taking fingerprints of the five fingers using fingerprint ink. But, it was found that all the fingerprints of the baboon monkey are characterized by one form and cannot be classified under any form of known fingerprint types. On the other hand, the ink fingerprinting showed a difficulty of taking a fingerprint for each finger of squirrel because of their hand small size. Thus, this study showed that there is no clear fingerprint in the monkey and squirrels, although the morphological structure of the hand in humans, monkeys and squirrels is similar to the simple differences in the use of hand in dealing with the surrounding environment. The scanning electron microscopy showed that there are numerous differences in the ventral surface of finger’s skin between samples of these three mammalian species.
